As a teen, I was obsessed with knot theory, and Conway's knot notation always felt like magic to me.

The notation works by counting the number of twists in a segment, and then looking for another twist directly connected to the previous twist, and so on.

This gives you a sequence of integers, one counting the number (and direction) of twists.

If the entire knot is made of twists connected this way, then the continued fraction you get from the sequence of numbers is a knot invariant!

Earlier quoted context omitted.

The thread on Twitter says yes but I'm not sure that's a reliable source.

Yeah, does anyone have a news source for this besides the one twitter thread? Wikipedia wants to know.

Colm is extremely well-connected in recreational mathematical circles. He's on the board of the G4G committee, and is an active mathematician and populariser of mathematics. It was he who first broke the news of Richard Guy's passing.

Anything he says is reliable, but by all means wait for other confirmation.

WRT wikipedia, I have a story about the Richard Guy page, but that's not a story for here. Another time.

Is there any confirmation of this? It appears absolutely nowhere else on the web.

The Princeton Department of Mathematics page doesn't seem to have anything about his passing. Edit: Of course it's the weekend; I should have realized that there will probably not be anything on that page before Monday.
